A Study of Bogu huahui: The Collaborative Work of Zhu Cheng and Ren Xun in 1872
No full text本論文以1872年朱偁、任薰《博古花卉圖四屏》作為主要材料，首先針對全形拓的目標與視覺效果進行分析，指明全形拓與既有圖繪的關鍵差異在於拓片能夠呈現器面的質感，而《博古花卉圖四屏》拓片的選擇說明對於器物形象的關注。其次梳理全形拓的製作方式，注意到全形拓其實相當倚賴繪製的草圖，而透過分析《博古花卉圖四屏》採用的拓片可以注意到不合乎器物結構的現象，說明此套作品採用翻刻拓片。最後聚焦於朱偁與任薰兩位畫家補繪花卉，透過補繪的物象位置與落款方式，可以知道此套作品是在任薰完成後，畫主蘭生再委託朱偁補繪而成，而《博古花卉圖四屏》此類作品之所以在上海盛行，與上海在十九世紀下半葉成為金石收藏與繪畫活動的中心關係密切。 本論文檢討前人研究將全形拓定位為機械複製器物的技術，關注全形拓與圖繪之間的關係，並透過《博古花卉圖四屏》結合翻刻的全形拓與職業畫家補繪的簡筆花卉，說明此類作品不再只侷限於特定的金石藏家群體，已經成為完全職業化的作品。The thesis focuses on the collaborative work of Zhu Cheng and Ren Xun in 1872. The first part of the thesis illustrates the goals and visual effects of composite rubbings. The main difference between existing illustrations and composite rubbings is the surface texture of bronzes that composite rubbings show. In the second part, this thesis reconstructs the way of making composite rubbings and indicates that making composite rubbings relies on sketching. Because the composite rubbings of the collaborative work of Zhu Cheng and Ren Xun in 1872 show some compositions that do not meet the structures of bronzes, there are carved rubbings in this work. The final part of the thesis focuses on how Zhu Cheng and Ren Xun painted flowers. By analyzing the positions of flowers we can discover this work is completed after Ren Xun painted it. However the owner Lansheng entrusted this work to Zhu Cheng again. Zhu Cheng and Ren Xun both worked in Shanghai. In the second half of the nineteenth century Shanghai became the center of the epigraphy and painting activities so bogu huahui prevailed in Shanghai. This thesis tries to revise previous studies that define composite rubbings as mechanical reproduction technology. The collaborative work of Zhu Cheng and Ren Xun in 1872 indicates bogu huahui no longer confines to a specific group of collectors, and bogu huahui becomes professional painting
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
